Deren's book on Voudoun was called Divine Horsemen: The Living Gods of Haiti, written in 1953. She's something like the mother of avant-garde cinema, not only before her time in the films she made, but also pretty much the only female working in film or the avant garde at that time. Her real name was Eleanora Derenkowsky, and she was born in Kiev. She went to Smith College, and was also accomplished in poetry, fiction, and dance.
